4 Keithley Metrabyte MID-64

Data Aquisition Boards


The MID-64 METRABUS Driver board interfaces the METRABUS system to the PC. It allows a single PC expansion slot to control up to 32 external METRABUS I/O boards. This allows a single board to interface to 512 digital or 256 analog I/O points. Programming the METRABUS system is very simple because the interface board generates all required timing and control signals. A 50-pin connector extends out the rear of the PC and connects to the METRABUS cable. The 50 conductor cable connects the METRABUS interface boards and power supply to the driver board. The cable carries all data, address, and control signals as well as power. Ground conductors are interleaved between all signal lines to increase system noise immunity.

The METRABUS system has been designed to allow cable lengths up to 100 feet. Applications which require communication
at distances greater than 100 feet should use the REM-64 remote driver card or INTMD64 stand-alone controller. The MID-64 uses 8 consecutive addresses. The addresses are set by a DIP switch located on the boards.

Equipment Notes:
